PURPOSE: To determine whether bronchoalveolar lavage (BAL) remains a useful technique in assessing human immunodeficiency virus (HIV)-infected patients with pulmonary symptoms. PATIENTS AND METHODS: All HIV-infected patients with pulmonary symptoms referred to a university hospital-based pulmonary service underwent bronchoscopy and BAL within 24 hours of referral. All samples were handled in a standardized fashion. The results of the lavage were compared with chest roentgenograms and clinical results. RESULTS: A total of 894 lavages were performed on HIV-infected patients over a 7-year period. The overall diagnostic yield was 60%, with 420 patients having Pneumocystis carinii. Infections other than P carinii were found in 185 cases, including 75 lavages with P carinii and another infection. The other infections included Mycobacterium tuberculosis (17 patients), Mycobacterium kansasii (15 patients), Histoplasma capsulatum (24 patients), Cryptococcus neoformans (17 patients), and bacterial infection (103 patients). For 364 lavages, no diagnosis was made. Chest roentgenograms were not useful in predicting what infection would be diagnosed. There was no difference in the yield of BAL over the 7-year period, despite the introduction of aerosol pentamidine prophylaxis and antiretroviral therapy. CONCLUSION: Bronchoscopy with BAL continues to have a role in the evaluation of HIV-infected patients with pulmonary symptoms.
